Circuit Breaker Retrofits

Retrofitting of low voltage circuit breakers is often an extremely cost effective way to modernize existing switchgear
Retrofitting of low voltage circuit breakers is often an extremely cost effective way to modernize existing switchgear while incorporating the latest technology into the system. In most instances breakers can be modified with little or no work required to the breaker cell components.

A well planned approach is the key to a successful upgrade. The first step includes monitoring present load conditions and forecasting future loads. With the load information gathered, the next step is to perform a Short Circuit and Coordination Study in order to assure the present system has the capability to handle the future capacity and determine the proper features and settings for the protective devices to be installed. The next step is to determine the systems ability to be shutdown. Can it be shutdown for a weekend, nights, days etc.? For how long? What is the availability of spares? Answers to these questions will help determine the need for replacement breakers versus an onsite retrofit. Last you will want to look at future requirements. Will want to add communications later down the road? Do you want added functions that you may have a future requirement for? Is the kit you are looking to go with upgradeable at a later date? Once you have answered these questions you are well on your way to a successful upgrade project. The next step is to look for a qualified NETA certified testing company to work with to ensure the quality of the installation and integrity of the final product.
